PINLESS HINGE.

SPECIFICATION forming part of Letters Patent No. 704,590, dated July 15,1902. Application iiled March 25, 1902l Serial No. 99,917. (No model.)

To all whom. it may concern,.-

Be itknown that we, DAVID SAMUEL STIM- soN and VAUGUSTUS STEvENsoN,citizens of the United States of America, residing at Kittery, in thecounty of York, in the State of Maine, have invented certain new anduseful Improvements in Pinless Hinges, of which the following is aspecification.

This invention relates to a pinless hinge, whereof the members arereadily separable from each other. This hinge is adapted for use inconnection with chests, sand-flasks for metal castings, scuttles,outside Windows, and many other purposes. It is especially useful forhinging the covers or lids of the mess-chests used in the United StatesArmy and Navy for the storage of'food, as these chests need to befrequently and thoroughly cleaned.

The principal object of the invention is to provide a separable hinge ofsimple construction which will permit the lid or other hinged part to bereadily separated from and restored to the chest or body to which itbelongs by unskilled persons and which will render the chest secure whenlocked.

Figure l of the accompanying drawings represents a perspective view ofthis pinless hinge, the parts thereof being assembled and in closedposition. Fig. 2 represents a transverse section of a corner of a chestor box provided with this improved hinge, one member thereof beingsecured to the back of the box and the other member to the lid or coverthereof, the latter being in closed position and a portion of thestationaryhinged member being in section. Fig. Srepresen ts a sectionsimilar to that shown in Fig. 2, except that the lid is in openposition. Fig. 4 represents a transverse section of the hinge throughthe pivot-joint thereof on line 4 4, Fig. 2. Fig. 5 is a diagramrepresenting the movement of the swinging portion of the hinge in theact of separation from the stationary portion thereof.

The same reference characters are used in all the gures to designate thesame parts.

This hinge comprises two members A and B, one being adapted to swing onthe other without any connecting-pintle. The member A may constitute astationary member, attachable, for instance, to the inner face of theback c of a chest, and the memberB may constitute aswinging memberfulcrumed on the stationary member and attachable to the inner face ofthe cover or lid dofsuch chest.

The stationary member A comprises an attaching-plate 10 and afulcrum-plate 20, preferablyintegral with each other, the fulcrumplateextending from one end of the attaching-plate at an angle thereto. Theattaching-plate is preferably provided with screwholes, as ll, for theattaching-screws. The fulcrum-plate comprises a depressed slotted curvedextension forming shallow open bearings 22,-in which the journal portionof the other hinge member turns. When the hinge is constructed forattachment to the interior of a box or chest, as shown in the drawings,the fulcrum-plate also comprises a hook 2l between the shallow bearingsand the attaching-plate. This hook engages the upper edge of the back ofthe chest, being preferably set in a recess therein. The hook portion ofthe plate is preferably provided with screw-holes for additionalattaching-screws. The curved extension 22 terminatesin a plane below theplane of the 4hook portion 21, and the ends 23 thereof serve as stops orrests for the swinging member of the hinge, as hereinafter described.The slotted curved extension is rabbeted on its under side adjacent toits slot for a purpose hereinafter described.

The swinging member B comprises an attaching-plate 30 and a pivot-fiange4.0, integral with said plate at one end thereof. The end of this angeis rounded, forming journals 4l and 42, which rest in the open bearings22. This flange is provided with a projection or button, as 50, whichengages the slot between said bearings and prevents lateraldisplacement. This button is preferably integral or rigid with thepivot-flange and preferably provided with lateral lips, as 5l, whichoverlap the fulcrum-plate and lock the members in assembled position.This button is preferably rabbeted on its under side and engages therabbeted edges of the arc-shaped extension 22. In this construction thebody of the button is extended below the outer face of saidextension,and hence it cannot be easily cut off to surreptitiously openthe chest, as might be the case if it were not thus slinken. A rib ortongue may extend from the but- IOO ton in either or both directions,being preferably truncated at its lower end and forming a beveled stop56, which comes against the under side of the fulcrum-plate when thehinge is open. A shoulder 57 is formed at the base of thepivotflange,and this shoulder rests on the ends or stops 23 of thestationary member when the swinging member is open. The lid is thusdoubly held at the desired angle when in open position.

The swinging member is provided near its pivot-ange with a stop 60,which may be in the form of a transverse cleat, which preventsdetachment of the parts of the hinge when the lid is closed. This stopthen engages the upper end of the stationary member A and prevents thebending in of the back of the chest to disengage the parts of the hinge.The meeting edges of the stop 60 and member A are beveled, as indicated,to permit the detachment of the cover when unlocked. This isaccomplished by` slightly raising the cover vertically and bodily and atthe same time moving it backward, as indicated in Fig. 5.

This hinge is very simple in construction. Each member may be castcomplete, and no pintle is required to connect the parts.

We claim as our inventionl. A hinge comprising two members, one having aslotted curved extension and the other having a rounded end journaled insaid curved extension, said rounded end being provided with a buttonengaging the slot of said extension and' overlapping the edges thereof.v

2. A hinge comprising two members, one

having a slotted curved extension and the other having a rounded endjonrnaled in said curved extension, said rounded end being provided witha button engaging the slot of said extension and overlapping the edgesthereof, the overlapping edges of said button and said extension beingrabbeted.

3. A hinge comprising two members, one

having a depressed slotted curvediextension and the other having adepressed rounded end journaledfin said curved extension, said end beingprovided with a button engaging the slot of said curved extension andoverlapping the edges thereof.

4. A hinge comprising two members, one of said members consisting of anattachingplate and a fulcrum-plate at an angle thereto, saidfulcrum-plate havinga depressedslotted curved extensiompand the othermember having a depressed vrounded end journaled in said curvedextension, said rounded end being provided with a button engaging theslot of said curved extension and overlapping the edges thereof. f

5. In a hinge the combination of a member comprising an attaching-plateand a fulcrumplate, said fulcrum-plate having a slotted curved extensionand a hooked portion between said curved extension and attachingplate,and a member provided with a rounded end journaled in said curvedextension, said rounded end being provided with a button engaging theslot of said curved extension and overlapping the edges thereof.

6. In a hinge the combination of two members adapted tov swing on eachother and close at right angles, one of said members comprising anattaching-plate and a fulcrum-plate having a slotted curved extension,and the other member having a depressed rounded end journaled in saidcurved extension, said rounded end being provided with a button engagingthe slot of said extension and overlapping the edges thereof, and saidswinging member being provided with a stop for engaging the stationarymember, whereby the parts are locked together when closed.
